POPSUGAR Celebrity

Justin Timberlake [1] has been goofing around on Jimmy Fallon [2]'s late-night show all week, but things really got ridiculous when Jimmy went shopping for a suit and tie with the help of JT, Steve Carell [3], and some mannequin arms. There's also a princess parody blowing up on the Internet, and it's giving us real talk on life after the Disney ending for Ariel, Jasmine, and more, plus we've got a riotous "Fresh Prince" sing-along with Will Smith [4], a white-knuckle prank from a famous race car driver, and Game of Thrones re-envisioned as a high school drama.
